Montana Tech Bachelors Theses and Reports were written intermittently between 1928 and 1970. Their digitization and publication is an ongoing project which provides access to previously unpublished historic information in metallurgy and mineral dressing, metallurgical engineering, geological engineering, environmental science, geophysical engineering and engineering science.
